To'aZZ whom it may concern: I

Beit known that I, HANs GLAUssoN HAN- snN,a 'sub'jectof the King of Norwa and a resident of the city of Christianiaj, Norway, manager, have invented a newand useful Improvement in Machines for Making such wise that the laths to be woven into the when they are being covered with plaster,

binding wires or strings.

cloth must bein'serted from the side of the machine between all the bearing and To insert these thinga'nd' fragile laths from the side of the machineisa very d-ifiicult and slow process, which reduces the outputting capacity of the machine. Moreover the'machines hitherto known act by always whipping the binding wire or string around the bearing wires and laths in the same direction. This involves the binding wire passingat'an angle over thelath's,whichmakes-their at tachment to the bearing wire less firm and secure than it "shouldbe, and thus the product is not as good as it otherwise might be.

The object of this present invention is,

that the weaving -can be done with the laths lying with their full length right across all the bearing wires and the laths are brought up by arms to the part of the machine where their fastening to the bear in wires takes place. This is rendered possible by the l'aths being laid on an'automatically sinkable frame, over'whi'ch all the bearing wires, in a tightly stretched'condition, fit into the machine, and togetherwith the laths are automatically raisedup into the position in which the fastening by the binding wires takes place. And further, the machine works in such wise that the binding wires whip-around the laths and bearing wires alternately with right and left turns, whereby the wire iscarried over the laths perpendicular to their axis, thus insuring a firm attachment of the laths-to the bearing Wires, so thatthe'y cannot slip j Specification of Letters Patent.

and thus cracks in the surface of the plaster are obviated.

An example of one form for such a machine is shown on the accompanying drawlngs.

Figure l shows the machine seen from one of the sides. Fig. 2 shows on an enlarged scale the whipping apparatus of the ma chine, seen from one'side with the lowerable frame 1n the position it takes when the whippingjwith the binding wire is a a'which is actuated by the driving shaft of the machine, and by the rod 5, this frame can be automatically lowered and raised. In Fig; 2, the frame "is shown in dotted lines in depressed position. f

6 is an 'arm which brings the laths 7, that are placed on the bearing wires, up to the position in which ,their being whipped on by the binding wire is effected. Several arms are provided which are fixed, at suitable distances, to the axle 9, which is turned by a lever system, worked by the machine operator by'means of a pedal that is not showno'n the drawing. The arms 6 are returned to their original, inoperative position by means of springs 8.

-The bearing wires 12 are led into the machine over the frameji, and are tightened between ordinary holders 10, by the adjustable stretching screws 11. When the frame isdepressed, theiath 7 is placed on the bearing wire 12, which goes over the frame, and on raising the frame, the lath 7 is conveyed by the arms 6 tothe place where the fastening on takes place by the binding wire 13. a

The whipping by the binding wire is done by the whipping apparatus 19, which is journaljed in a bearing 18 and is furnished with a-tooth'ed portion and has a slit 21, going to the center. When the frame has been brought up into a horizontal position, the

bearing wire wil'lthen be in the center of The whipping by the binding wire is done by means of the rack-bar 25, which is operated by the screw 26, the longitudinal displacement of the rack bar 25 being effected by rotation of the screw, so that the apparatus, with the binding wire, makes three'or more turns. 'When the lath is fastenedto the bearing wire by the whipping apparatus, the cloth is fed forward in'a well-known manner by means of the toothed roller 16, which is given a step-by-step revolving motion by means of a ratchet-wheel mechanism, not shown on the drawings, by which the cloth is carried forward to such distance as that which it is desired to have between the laths. The finished cloth is wound up on a drum '17. Meanwhile the framehas againbeen depressed, and upon it another lath" is placed, which is conveyed to the fastening apparatus and is fastened to the bearing wires by the rack bar 25 as it goes back. It will thus always whip on the binding wire in the opposite direc tion to the previous one, and thus in such wise that the bindings will alternately be in opposite directions, whereby the binding wire willalways pass straight over the lath perpendicular to its axis.

Having nowdescribed my invention, what I claim is:

1. In a machine for connecting longitudinal supporting wire with lath, a twisting apparatus, a holder for the supporting wire, and means for alternately bringing the said holder into operative and women ative position with respect to the twisting apparatus.

2. In a machine of the character described, the combination of a' holder for 1011- gitudinal supporting wires, a twisting apparatus, means for moving the holder in longitudinal supportingwires, and means for raising and lowering said holder alternately into operative and'inoperative pos1-' tion with respect to the twisting; apparatus.

'5. In a machine of the character described, the combination" of a twistingapparatus secured to a-stationarypart 'of the machine, a holder for longitudinal supporting wires, and independently operable means for conveying lath on'the holder into a position in which the twisting apparatus acts on the" lath and supporting wire;

6. In a machine of the character described, the combination of a twisting apparatus secured to a stationary part ofthe machine, a holder for longitudinal supporting wires,- and a plurality of goscillatable arms adapted to engage a lath onthe'holder on a plurality of points and to convey the same to the position, where the connection between the lath and supportingwire is cf fected by the twisting apparatus. I

7. In a machine of the fcharacter described, the combination of a-twisting apparatus, comprising a rotary; support for the twisting wire, a holder for the longitu:

dinal supporting wire, and means for moving the supporting wire alternately into and out of the axis of rotation. 8. In a machine of the character described, the combination of a twistingapparatus having a disk, a means forsupporting the twisting wire'on said" disk, a groove in said disk, means for rotating the twisting apparatus aboutsaid groove, and means for placing and removing alternately alongitudin'al wire into and from said groove.

9. In a 7 machine of the character, described, the combination of a' twisting apparatus, a holder for longitudinal supporting wire, and means'for rotating the twisting apparatus alternately in opposite direcscribed, the combination'of a rotary twist ing apparatus secured to a stationary part of the machine, a spoolfor twisting wire on the apparatus, guiding means for the'twisting wlre disposed parallel to the axis of-rotation of the apparatus, means for {alternately bringing a longitudinal supporting wire into the axis of rotation and forremoving it therefrom, andindependently operable means for advancing a lath in the direction of-the supporting wire in the interspace between the twisting wire and the supporting wire.
